Ray, 
 maybe that   in   /etc/ssh/sshd_config    you are using  the default   :

...
£UseDNS yes 
...

Check  if in  /etc/resolv.conf   the  " nameserver  x.x.x.x "    is 
correct  (ip  of DNS ) 

Otherwise set 

 UseDNS  no 

 or   comment    # nameserver  x.x.x.x     in    /etc/resolv.conf 


Cordiali saluti  / Best regards
 

        Marco Bosisio

Logon password prompt delay

Hi,

I'm trying to figure out why some of our SLES10 images have a 5 second
delay before prompting for the password during initial SSH logon. It
only happens once; if I put in a wrong password, it re-prompts
immediately. The images that have the delay are clones of the original
which does not have a delay. After cloning I changed eth0, HOSTNAME,
hosts, resolv.conf, and routes to their new values. nsswitch.conf is the
same.

I did some experimenting with CA PAM authentication a few months ago,
but have since turned it back off. I checked with the z/OS admin to make
sure there was nothing coming in from Linux. This is a relatively minor
issue, but I want to make sure it doesn't precipitate a bigger problem
down the road.
